3) Solve the problem. For large numbers of degrees of freedom, the critical x values can be approximated as follows: =-( z+/2k –1), where k is the number of degrees of freedom and z is the critical value. To find the lower critical value, the negative z-value is used, to find the upper critical value, the positive z-value is used. Use this approximation to estimate the critical value of x in a two-tailed hypothesis test with n= 104 and a= 0.10. .
